Like symbols refer to like parts 'Whereyer they occur.

I will now proceed to describe my invention morefully so that others skilled in the art to which it appertains may apply the saine.v

In the drawings. A indicate thc usual longitudinal skids orsills for the support of the machine, vand ll the hed-plate,which in my construction I locate directly on the skids S0 las to eliminate the commonly employed with ipping rolls, and covered seats or nutA pockets for the nuts of the clamp screws. I'

eeaoso cross timbers and thus lower the machineto y a position which Will enable the operator to use with ease the requisite lgools in manipulating the tubing. This hed plate B which supports the annular rotary plate or turntable C, is provided on its under surface arallel pendant ribs Z) suiiiciently space to accommodate the longitudinal skids A, A, rand said ribs terminate or are interrupted at the central opening of the bed-plate B provided Afor the passage of the drill pipe. AThese ribs serve not only to strengthen the structure, but maintain the parallelism .of the skids A, A, and insure the rigidity of the machine. Extensions Z3',

Z2 of the bed plate provide a suitable support :gid points of attachmentfor the hearing of the driving shaft which actuates the turn-table. The up er surface of the bed-plate B is provide with an annular groove or race-wa 2 for the rolls r which support the annu ar rotary plate or turntable C, and said hase-plate is bolted or otherwise secured to the skids A. A in any ap roved manner.

j indicates the annular rotary plate or turn-table provided on its under surface with an annular groove or race-way c corresponding to the race-Way b2 of the haseplate B, for the reception of the rolls r' which support the turntable and on which it travels. To the inside of vrace-Way c the turn-table is provided with av pendant annular flange c which extends down into the pipe opening of the base-plate, and in its peripherv above the racewvay the turn-tahle is provided with an annular groove or recess c2 for the reception of a thrust-ring E which anchors the turn-table to the hase-plate. The upper portion of the table is provided With an overhang or flange C on the under surface of which is formed an annular "rack R with Which the piniony on the driving shaft M engages. lxteritna to the annular rack R in the `under side of, the overhang C is an annular groove er channel forming a counter c* 'which deiiects the muddy water of the table and prevents it from entering and ahrading the gear. The upper surface of turn-table C is depressed as at CL tio accommodate the drive-ring F and is provided with holes c5 for the drive-pinsG. The drive-pins are secured t the turn-table by cross pins c inserted through holes in the table in the plan-e of the groove for the ping rolls, and which is carried. hy the ro-Y 1 tary' turn-table C. It is caused to rotate with the turnftahle hy means of the drivepius (l secured k1n the upper surface of the turn-table. The drive-r1ng is provided at diametrically opposite points on both its upper and under surfaces with bosses f,

vor elosed ahove so that no 1 which are bored or otherwise hollowed out to -forln 'por-.lieta for the reception el.I the drive-pins G', G which projeetviron'i the upper surface. of the t urn-table. The bosses f, .f located on the upper surface ot' the drivea'ing l? are U-shaped in cross section' movement of the drive-ring on the drivepin's. It iyillalso benoted that the bosses f are provided with Ypin holes f* and the drive pins G are likewise provided .with pin holes y, so that; the drive-pins G can be seeuredxto the drive-ring well to the turn-table, if the saine desired. There is, however, another and more important function for the pin holes ft, viz., the reception ofi-pins to de- :and turning the drill-tube or drill` rod.

K. l( indicate the clamp-tiramos which carry the gripping rolls. These trames are ot' a general liox form,l that is to say, are each covered or closed abpve,' beneath andl on the outer sideV so as to exclude muddy water, sand/and grit as far 'as practicable, but are open on theinner side for the reception of the gripping rolls and the projecting ot'ithe o ierative portions thereof. u n the interior o each of said frames adjacent to the ends thereof are bearings le for the' shafltp'of the gripping' rolls, and projecting inwardly at' midle-ngth is an intermediate bearingvor snp- .poi-tk forthe shaft of the gripping rol se that the clamp-frames have the charaeter isties of beams for transmitting the load of the elamp-serews directly to the rolls` and drill-tube, and the 'shaftsof the rolls are prevented. from springing so as to weaken the gri of the rolls onthe drill-tube or dri lrod. A t the ends ofthe elainp traine are holes k2 for the passage of the clanlp-screws ll, il and haelt thereof 'are nuti pockets Vlr of vthe general t'orin ot' nuts ll. for the reception et .said nuts. The least' diameter .of said nut poelsets 1.13 slightly vexceeds thegreatest diameter oi the nuts l I' (see Fig. '7) so as to lpermit the easy intreden-tion ot' the nuts into the Apockets 1, hut Within the month ot the pocket the pocket expanded to forni a cylindrical ref-ess or suli-poelret. l# tor the reception ofit'he oyl'indrieal liess or ott'set 7b2 of the nut Il. The excess et' the diameter 'of the nut-pocket, over that eff the nut whieh permits the nui'- with its cylindrical hess to he easily introduced into the nut pocket', also permits a limited vertical play of the nut` so that the nntwhile sustained 'by the,rlainp-sorew may he said to constitute a floatingvnunet-tion hetween the olanda-screw and elan'ip'tranie. i Y

These rolls may ment ot disks'on the shafts Z, Z heini;4 such as -to so space the disks of greater diameter luy theinterposition of-disks ot. less diameter y as to obtain' the desired edge'grip of the' 120 larger disks on a drill-tube oi? any lrequired diameter.

This'. shaft Mend '125 `its"-bearings. D, D, are in alineinent, and the" shaft extends radially toward the airis of rotationI of the rotaryI table C.' i This driving shaftmay be driven freni' lanysuitable roo-Vv handlin wheel mi loose on the shaft M and-operatively connected thereto by a clutch member 'm2 spline-d on and rotating with the. shaft.

In order to shift the clutch-member m into and ont ot engagement with the sprocketwheel m a (clutch-lever n connected with a rock-shaft N journaled on the sills A., A, said rock shaft extending at right angles to the shaft M, is employed, and on the stuli end of the rock-shaft N which actuates the clutch lever n is loosely fitted a short piece of pipe li as a protection under the-severe incident to the use of the machine.

It wil be noted that the arrangement and construction oi the clutch vlever is such as to locate the handle away from the shaft and on the side toward theoperator which enables the clutch to be more readily operated and without exposing the operator to danger.

As hereinbefore pointed out, the pinlonshaft M is journaled in suitable bearings D secured to the bed-plate B. I construct the bearing D for the shaft M with a pillowbloclr d andcap d divided on a plane'inclined to the horizontal (see Fig. 8) which brings thepi'essure o'the shaft against the. solidl or bottom portion-of the box d leaving the cap free from pressure, so that the cap d which is connected with the pilie"'hlock d by the boltsdg always remains securely in place. As a result of this construction of the sha-ft bearing, taken" in connection .with the relation of the shaft to the sprocket wheel and driving chain and the turn table driven by the shaft, the pull of the chain is counteracted by the reaction of the driving gear, so that the Wear on the bearing and shaft and the injury to the machine-ry frequently-occurring where a horizontally divided bearing is used in such a combination, are obvi- Vated. The under surface of the pillow-block 1al is provided'witli pendant. lugs cl3 whioh engage the bed 'and oppose the pull of the sprocketwheel m and the resultant pressure from the gearing, thus relieving the bolts from all shearing stresses.

Thetlirust of thetnrn-table is taken up and transmitted tothe bed-plate by the thrust ring E, as hereinbelore noted, lThis thrusty ring E which has its seat in the peripheral groove c2 and thus maintains a continuous bearing on the periphery of the turn-table, is

coin posed of a plurality of sections e, e, preferably two, which, after application to the turn-table, are bolted together as at e', and said sections are provided with aplurality of pendant straps or foot extensions e2 by means of which the thrust-ring is secured to, or anchored to.-the bed plate B. This construction not only insures uniform support ofthe rotary table at all points on .its periphery but it causes the co-action ofthe several straps e2 in support of the individual strap under the thrust .of the rotary table when that thrust is inthe line ,of an individual strap. Furthermore, such a construction permits of the use of shims e between the straps a2 and bed plate B to provide for taking up wear and lost motion.

The construction of the several elements of the machine being substantially such as hereinbefore pointed out, they may be assembled as follows: The drive pins G will be inserted in the holes d5 of the turn-table C, and secured by the cross-pins e. The disks constituting the gripping rolls L, L will. be properly assembled on their shafts l, and the rolls inserted in the clamp-frames K, K. The skids A., A, or longitudinal sills which are to support the machine, are properly placed and spaced, the bedlate B deposited di# rectly thereon with tie pendantiribs b between and in Contact with the inner sides of the sills to maintain the alinement of the sills, and the bed-plate is secured to the sills in the usual manner so that great rigidity of the bed-plate is obtained. The driving gear is then alined with the bed-plate and secured thereto and to the sills, the rollers i' are placed in the race-way b2 in the upper sur,- face of the bed-plate, the turn-table is placed in position on rolls v" and the bed-plate, the thrust-ring sections e, e are applied in the peripheral groove c of the turn-table and are bolted together, after which the pendant straps or foot extensions e2 of thrust-ring E are bolted or otherwise secured to bed-plate B. The drive-ring F will then be placed dn the turn-table with the drive-pins G projecting into the tubular bosses f,f of the drive- 100 ring, after which cross pins may be passed through the openings f* of the bosses and through the drive pins G'. The clam screws H, H will then be connected Witht e drive-ring F by insertingy the enlarged prismatic portions la thereof in the yoke or fork f2 of the bosses f, the nuts H', H', will be inserted in the nut pockets lf3 of the clampframes l, K,'after which the lclamp-frames K, K will be placed in propel relation with each other and with the clamp-screws H, H,

the ends of the clanp-screws inserted into the nuts H', H through the holes lo? at the ends of the clamp framepand thefclamp-screws rotated unt-il they have engaged the nuts H", H', and drawn the clamp-frames toward each other the desired distance. When. thus assembled the machine is rea-dy for service.

In operating the machine, the elarnpi. frames are drawn toward each other by the clamp-screws until the gripping rolls have obtained the required hold on the drill-pipe to rotate the4 turn-table, the'fdrivethe clamp-screw, clamp-frame andngrippinaf. rolls, and thus rotate the l drill-tube or drillrod. If at any time a blister should open on the drill-tubefrom the grip of th gripping rolls, and il, should heconie desiralile to clianejo the location ot thegrip of the rolls on the -drill-ljiiprn the rotation of the talile Will be stopped, the cross-pins Will be Withdrawn from the holesy f olf.' bosses f and the holes g ol' drive-pins` (fr, and power applied to raise the drill-tube. The drill-tube when lifted uiill carry up with it the gripping rolls L, i. elanip-lframes K, clampeerews H, H, and the drivri-ring.;V lt". When thied has taken )lace the eross-pins may be replaced in the lioles f* of the bossesf ot the drive ring, and the drill-tube lowered so that the erossfpins rest.

upon the tops of drive-pins G which will Ihohl the drive-ring elevated above the table while the weight of the drill-tube will canse it to sink through the griliiping rolls until a new grip higher up on the drive-tube will be secured. The power can he again applied to rotate the turn-table and the drilling operation proceeded with as before.'
